Bat Ray (Expert)

About this fish

Bat Ray (Expert) is a saltwater shark-and-ray (eagle ray family) for advanced aquarists. In most aquarium trade listings, “bat ray” refers to Myliobatis californica, a species known for a broad pectoral “wing” disc and a whip-like tail. This ray is practical for very large, dedicated marine setups where it can graze along the bottom for prey and be fed an appropriate meaty diet. Because rays are sensitive to water quality and require specialized, spacious life-support systems, Bat Ray (Expert) is intended for experienced keepers only.

• Bottom-associated feeder: bat rays hunt and eat mollusks, crustaceans, and small fishes. ([montereybayaquarium.org](https://www.montereybayaquarium.org/animals-the-ocean/animals-a-to-z/bat-ray?utm_source=openai))
• Large adult size means long-term planning for system capacity and floor space. ([montereybayaquarium.org](https://www.montereybayaquarium.org/animals-the-ocean/animals-a-to-z/bat-ray?utm_source=openai))
• Generally non-aggressive in behavior, but as a ray it should be housed with care to reduce stress and prevent injury. ([floridamuseum.ufl.edu](https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/bat-ray/?utm_source=openai))
